 same in number opposite; filaments central or inserted around 

 minute rudiment of gynsecium, free, straight or incurved at apex ;

 flower in polyphyllous involucre solitary free ; bracts of involucre 

 unequal, imbricate in many series. Calyx conical gamophyllous, 

 prolonged upwards to a tubular neck, 4-dentate at apex. Germen 

 free sessile unequal, prolonged at apex to a narrow slender style, 

 afterwards 2-fid ; lacinise linear elongate recurved, papillose at subu- 

 late apex. Fruit dry, indehiscent, covered with fleshy perianth; 

 seed . . . ? — Lactescent trees ; leaves alternate petiolate, entire or 

 remotely dentate or sinuate, sometimes somewhat rough or pubescent ; 

 stipules 2, amplexicaul oblong imbricate sericeous ; flowers axillary ;
